It is known that there exist hand switches intended to short-circuit thelighting dynanro automatic cut-out fitted in vehicles with explosionengines with the object of making the equipment operate without the aidof the battery. Nevertheless these hand switches do not insulate thebattery and only short-circuit the automatic cutout, thus making itnecessary to break the circuit of one of the cables of the batteryterminals. 10 Another inconvenience is the fact t at with a batterycharged, if the switch is left in he dynamo position, the batterydischarges, when the dynamo is at rest, back through the dynamo.

The hand switch forming the object of the pres- 15 cut invention hasalso the aim of short-circuiting the automatic charging cut-out, but ina quite difierent way, by completely insulating the battery from theremainder of the installation. In addition this switch is made up insuch a way that it at the same time enables the current in the inductorsto be switched oil and the dynamo to operate on the poles constituted bypermanent magnets.

The invention can in any case be well understood with the aid ofthesupplementary description below and of the attached drawing, whichdescription and drawing are, of course, given above all by way ofexample.

Figure 1 represents the switch in the battery 30 position. I

Figure 2 is a straightened section of this switch in the batteryposition, through the line 2-2 of Figure 1.-

Figure 3 gives the view from below.

35 Figure 4-represents the switch in the dynamoposition. Figure 5 givesthe plan for mounting in a vehicle,

said switch. I

Figure 6 isa modification of the main switch of the invention,illustrating the inclusion of a third or intermediate contact position.

Throughout the views, the same references indicate the same orcorresponding parts.

In accordance with the invention the switch A shown in Figures 1 to 5 isa two-way switch.

It is constituted by a plate I acting as support 50 for thecontact-studs 2, 3, 4, 5, 6, and l.

A spindle l l supporting contact strips can turn in the centre of theplate and can make the strips assume the positions X (battery) or Y(dynamo). One contact strip 8 is riveted to the rotating 55 spindle Hand can bring into contact the studs Figure 5a is an obverse view of aswitch of Fig- 40 ure 5 showing the rear of two connections upon July27, 1933 5 and 4 in the position X and the stud 6 and the spindle II inthe position Y;

Another contact strip 9, riveted to an insulating washer l0, insulatedfrom the spindle H and the strip 8, brings into contact in the positionX the two studs 2 and 3.

In addition a sunk stud l is in permanent contact with the spindle l Iand the strip 8=by means of a brass plate i4.

In the position Y of the contact strips (Figure 4) ,"the studs 6 and lare only in contact through the strip 8 and the spindle ll.

-In order better to understand the operation of the apparatus it is onlynecessary to refer to the diagram given in. Figure 5, and also Figure 5awhich shows the obverse side of switch 20 of Figure 5. This switch maybe made of a plate of molded insulating material supporting the brass ormetal contact pieces b-c--dP-e f-g -h -i.

An axle 7' is in electrical contact with the connecting or contact arm nis rotatable in the center of the plate and causes the contact pieces totake various connections.

The contact pieces 71. and i carry spring and p,

which latter are insulated from each other by an air space, but saidcontact pieces 71. and i may be connected by means of the key 22 whichis made of brass or any suitable metal and placed between the springs oand p which exert pressure on the key so that it is consequently wedgedand elec-- trically interconnects said two contact pieces h and i. Thelatter contact i being connected to the wire 24 coming from the maincontrol switch A and one of the wires from induction coil 23.

y of switch 20 and the contact h to which is connected the wire 21communicating with contact I of the main switch A. The switch 20 is fedby the conductor 21. If the key is introduced between the springs o andp, the current is sent through the wire 24 and into the coil 23.

By manipulating the axle i, it is obvious that electric current may besupplied to the various lamps at the extreme right in Figure by causinga contact arm (not shown) to engage any one of the corresponding lowercontacts in known manner within the range of said arm.

Returning now to the mentioned diagram, I5 is thetwo pole dynamorepresented schematically by the collector, the brushes, the inductorsI1 and the poles I6 which are constituted by permanent magnets. I8represents the circuit-closer, I9 is the battery which is joined by aconductor 26 to the contact stud 4 of the special switch A forming theobject of the patent. 20 is the switch The contact arm n makesconnection between axle= switch A. The contact key 22 passes current tothe ignition coil 23 and to the inductors H of the dynamo through thestrip 9 and the connections 24 and 25.

The circuit-closer l8 has a terminal joined to the stud 5 of the switchA by the connection 28. A wire 29 joins the'dynamo directly to the stud6 of the switch A. j In the case of battery ignition the operation is asfollows:

The contact strip of the switch A being in the position X (battery) andthe contact key 22 being placed in the switch 20, the inductors areunder tension from the battery through the connections 28, 4,8; I], 21,22, 24, and 25 and the contact strip 9. The dynamo operates with themagnets I6 and the supplementary inductors i1; It then chargesthebattery l9 through the circuit-closer, the wire 26 and the contact strip8 joining the contact studs 5 and 4 of the switch A. The equipment thenfunctions normally.

Let us suppose that the battery isshort-cir: cuited or damaged.

We then pass to the position Y of the switch A.

The strip 8,no longer being 'on the contact studs 4 and 5, then removesthe battery 19 from the circuit. The inductors I! are also'switched out,thestrip '9 no longer being on the contact studs'3 and'2.

The contact strip 8 is then on the stud 6 and connects it to the'stud I.The dynamo is only operating on the magnets IS; The current produced bythe dynamo is thus passed to the switch 20, which can supply current tothe lamps and to the ignition coil, the accumulator battery being out ofcircuit.

andof suppressing the action of the inductors on the dynamo.

In Figure 6 a modification of the main switch is diagrammaticallyillustrated showing how three possible positions'may be assumed by theswitching member for the purpose of avoiding overcharging of thebattery. In the third position, the switch cuts out the inductors andthe dynamo charges the battery, the magnets only producing the fluxnecessary for the operation of the dynamo. For thislpurpose a contactstud 3| is interposed between the studs 5 and 6, this being joinedto thestud 5. At the side of the stud 4 and opposite the stud 3| is located astud 32 joined to the stud 4.

In this position (position Z, for weak charging); the dynamo operatesonly on the magnets IS, .the inductors being switched oif by means ofthe strip 9. The studs 2 and 3 no longer beingin contact, the dynamothen charges the battery with a weaker intensityo'f charge. Torecapitulate, the device involves a rotary shaft ll, electricallyconnected to a lower contact disk l4,

rigid with a double contact plug 8 and another double contact plug 9from which said shaft 8,086,099 controlling the lighting and ignition inthe veis to say that the generator supplies the battery by theintermediary of the switch.

If the switch'is placed on the generator position, the inductors are cutfrom the generator and the battery is cut out of circuit with regard tothe principal current; the generator then works in such manner thatthecurrent arising in the armature rotating in the magnetic fieldcreatedonly -by.permanent magnets is immediately directed to thereceiving apparatus, such as, ignition coil, lights, signaling,instruments,

As is obvious the invention is not limited to the sole methods forcarrying out the invention given above solely by'way of example; .quiteto the contrary it embraces all variations within the scope of theappended claims.
